Excellent product. I have been using Demon WP Insecticide for MANY years mostly for exterior barrier treatment and in and around garages. I was very impressed. I will never forget the first time I used this product. I sprayed a heavy line in front of our 3 car garage which was getting bombarded by all kinds of crawling insects. It created about a 10-12" line on a hot & sunny day and it dried very quickly. I did it a second time thinking it evaporated, again it dried within a few mins. Came home from work the next day and a solid line of dead bugs exactly where I sprayed. Was as if it was an invisible electric fence. At this point I was sold on this and nothing else. I have continued to use it for years without fail. I found it lasts quite a while but depends on how much direct rain the treated surface area gets. Recommend 100%

"It just works" says it all. I have been using Demon WP Insecticide for 10 years. Forget what you read about multiple applications per year. Maybe outside, but inside, unless you wash or vacuum it away, it lasts forever. I haven't used it in 2 years indoors and it's still killing. I thought, after two years, though, another application couldn't hurt. The first time you use it, when you wake up the next morning, you will be in awe of the dead insects in your house. Just do every base board, even in cabinets and closets and every threshold into your house, garage, carport, etc...threshold exteriors need to be repeated if exposed to the elements. This stuff is the last word in pest control. Don't waste your money on supermarket and building supply store junk and pest control companies that come out and use this same stuff, and bill you $250.

This stuff is awesome!
By Kevin on 08/28/2007
I have 2 large dogs in my house. Had fleas really bad. I tried every type of bug bomb- Home Depot, Lowes, and Walmart had and it seemed like they multiplied. My parents turned me on to this product Demon WP. I sprayed my baseboards, windows, doors, weep holes in the brick, the entire perimeter of the house, the soffit on the house, and the perimeter of my yard. After all that, I still had 2 pouches left, so I went ahead and sprayed my lawn. I have not seen another live bug in the house for 2 years. I may not have applied it the way I'm supposed to, but this stuff is awesome. Highly recommended.

Try it and you will be satisfied!
By Chris on 02/21/2006
I have used Demon WP and I know it works . If you have a roach problem in your home this will kill them and will keep killing for months . It goes on wet and dries to a powder . You will be seeing dead roaches in 24 hours and 1 application will last months of killing power . It is safe too, I have pets and a small child and have never smelled or had a problem like pest control services cause . Try it and you will be satisfied.

Try this product!
By Joyce on 07/06/2008
Great product!! I've been using this product for 2 years and living by the ocean, we have our fair share of palmetto bugs, roaches and every crawly bug known to man. Demon WP keeps the house insect-free and considering I have a bug phobia, this means a great deal knowing that there aren't any unwelcome pests crawling around our home. Anyone having a problem with bugs should try this product...you'll be glad you did!!

Demon WP does the best job killing roaches with the fastest knock-down I have ever seen . However, for spiders it doesn't fair so well in my opinion. Only complaint is it leaves a slight stain on wooden floors and baseboards . It keeps killing a long time so re-spraying is only like 4 or 5 times a year . That itself will save you a bundle of money on exterminators.

Forget the exterminator!
By Jake on 07/11/2007
I had just put on Demon WP inside and outside my house to control earwigs and roaches, a day later I saw a few dead roaches in my garage and a few outside along with a Black Widow! I didn't even know I had those. I feel a bit safer knowing that my 2 year old, 3 month old, and small dog should be safe. Well, I don't know about my 2 year old. He's in everything ;) The local pest control service wanted 50 dollars a month to get rid of bugs or 150 for a one time application. For 15 dollars and 4 treatments that probably will work better anyway. Forget the exterminator :)

My mom owns a house out in the Texas HillCountry that has become somewhat of a weekend home and never had anyone truly live in it. When anyone had the time to go to the house it was expected to find at least 3 scorpions in the house. And during a weekend visit, we'd probably kill at least three more just inside the house. One even fell off the ceiling while we were having coffee and landing right in the center of the table. They thrive at this property, almost literally in every nook and crany both inside and out. I was referred to a different product on this site but reseached more and felt the Demon was better suited to our scorpion infestation. It worked! It took two batches to saturate the indicated areas on the outside of the house and I did not even spray the inside. Over the course of a week I found only two scorpions inside and one was already dead and the other dying. TRIUMPH! It's been another week since I've been at the house so I am curious to see how it is doing over the course of some passed time. I will update after a couple of months as the treatment says it should not be necessary but about once every 3 months. The only downfall is that with any poison you do end up killing other bugs you may not want to. There literally was bug carnage along the perimeter I created on the patio...everything from locusts, cave crickets, spiders but I was sad to have killed two rather impressively large stick bugs.

One month after we moved into our home we started to realize we had a serious problem with spiders, particularly Brown Recluses. Most other spiders died relatively quickly using average over the counter pest control measures, but the Brown Recluse was particularly resilient. After some scary moments and worthwhile research I decided to give Demon WP a try. I prepared the mix and applied the spray directly to a spider and was expecting to see it die within 1-2 seconds and although it didn't immediately kill it, it was dead within 20 minutes. I applied this product in the house, the crawlspace, the exterior of the home and I couln't be happier! I have found many dead Brown Recluses. I used sticky traps to monitor movement and they have stayed clean. This product is fantastic and is definitely effective at ridding your home of Brown Recluses and protecting your family!

Bye Bye Roaches
By John on 08/27/2010
Best product I have used to date. One application ended the Roach infestation we have suffered for years. Originally I balked at the price, however the end results well justified the cost. Unit was ordered and received in about 6 days. Superior rating in my book.

Long time users
By Patty on 04/10/2009
We have been using Demon WP for about 30 years. We hit a slump with kids and business draining us and couldn't afford the luxury of Demon and used some less expensive products. Yuck! They would work a little bit, wear out soon with a residual of about 6 weeks. With our kids grown and gone now, we have decided to go back to Demon. The real residual effect is more like 6 months and the day after we spray we find roaches sleeping the eternal sleep all over the house. Upside down, if you know what I mean. It's a wonderful product and I recommend it to anyone who asks.

Greak knockdown and residual power
By Michael on 06/25/2010
This product has been an industry standard for many years. Roaches don't have a chance against this product when properly applied. It works great on spiders as well as most household pests. Because it is a wettable powder (WP) it will stay on surfaces much longer than a liquid product. Another great feature of this product is safety. A human would need to consume several liters of this mixed product to be fatal. When applying this product to the exterior of a home be sure to cover the area around windows, the eaves (for spiders) and the base of the home. This will kill the majority of pest before they enter the home and the residual power of this product will hold up over a month outside. In some applications the residual power can even hold up for a year. A 1lb jar could easily treat a standard home for 3-10 years. Much cheaper per year than almost any hardware store product. NOTE: If you apply this product to dark surfaces you will get white powder that is very visible and can be hard to remove.

Easy to use! Highly recommend
By Dee on 07/13/2007
I sprayed this Demon insecticide in closets, under cabinets, appliances and outside of the house. I see a lot of dead bugs now and no live ones. It even killed a few spiders and other bugs outside the house. It is easy to use with a pump sprayer . I would highly recommend it to everyone . Thanks and I will buy again .

Awesome product. I've used it for over 10 years in my office and now in my home on 5 acres. It, along with a once over my immediate yard with insect granules in the spring, limits the outside cockroach problem to only a few stragglers a year due to open doors and/or windows. I spray the base boards and the perimeter of the house each year and we're covered. In this part of Texas where its hot and humid, Demon WP is a tremendous relief. Thanks!

Demon WP Insecticide powder works wonders for controlling bugs outside, and you don't have to spray chemicals inside your house. Very pleased, been using it for 4 years!

I am completely satisfied with this product. I've had ant problems for two years and after applying Demon WP the ants are all gone. I have not seen one ant or roach in months. First, I had to hire a professional who could not get rid of the problem so I decided to take matters into my own hands and glad I did. I saved a ton of money.

I used Demon WP last year to control asian beetles (lady bugs.) It kills them on contact, and kills them for the remainder of the fall season. By spraying it outside the first day I saw the beetles come to the house, I was able to keep most all of them from entering and wintering in the house. This year I am going to order a pound tub and spray the out buildings as well as the house.

We have used Demon WP Insecticide before in another state. It was very effective in killing spiders, water bugs, roaches, etc.

Great for indoors and out
By R. on 05/06/2008
I have been using Demon WP since 2001 and it's the best I have found for inside and outside applications. I don't even consider anything else.

I received this product as a gift from my sister and have been using it for several months. There is no doubt that Demon WP is by far the best product I have ever used for killing any/all inside/outside/ household pests.

Amazing product. I had a problem with crickets in my garage. The day before I used Demon WP, I tried the Ortho Home Defense spray that you can get at any home improvement store. Ortho worked to kill crickets if I sprayed directly on them. I killed all the crickets I saw, but a couple of hours later there were a ton more, even though I had sprayed all the cracks and crevices. Well, the next day, I received Demon WP along with the plastic Chapin sprayer. Usually there are at least 20 crickets all over the walls of my garage. This morning, I went into my garage and checked again. This time there were a bunch of crickets on the garage floor...but they were all dead. Demon WP definitely works!

I have used many products to eliminate roaches with marginal results (they promise but do not work as advertised). I finally purchased Demon WP and wow! The impact was immediate! The Demon totally eliminated the pests like never before. I will use nothing else from now on. One application and evidence was dead all around the application areas. No bugs have returned, either! Thanks to the many reviews, I purchased this product and it more than delivered. Great product.

My daughter wouldn't come out to our new ranch because of the spiders and scorpions. One application of Demon WP Insecticide got rid of every last one around the house and barn! Like someone else here said, we find a row of dead bugs, spiders, scorpions, even flying insects like wasps when we arrive every weekend. They are all lined up along the "spray line". It is an invisible fence! Now my daughter will come out because she is convinced she is "safe" in the house etc. I highly recommend this product.

It just works
By Scoot on 10/15/2010
All I can say is, if you have a problem with roaches or spiders, this is what you need. It's hard to beat spraying around the garage doors in the evening and waking up next morning with dead bugs lying around. This product is deadly, and it keeps on killing.

My warehouse was taken over by fiddle-back spiders, despite having regular treatments from Terminix, they couldn't kill them. It has been 3 weeks since we used Demon WP and we're seeing only DEAD spiders. We used to see live ones EVERY DAY! It's so easy to mix and use that we are now doing it ourselves instead of paying Terminix.

Kills carpenter bees fast
By Rd on 05/06/2008
I have found that Demon WP is the only product that will kill carpenter bees when they start to bore.

Trying to save money during our current economic crisis? Our family cut down on dining out, movies, and new clothes (we have found great buys at Am Vets and Goodwill thrift shops). We also suspended our lawn and pest control services. Our pest control service was costing us $39.00. We live in central California, the agricultural capital of the United States. Because of the many crops that our region grows we have numerous pests. After we stopped our pest control service we were invaded by a variety of nasty pests. Especially Daddy Long Leg spiders. Hundreds of them! We paid a visit to Lowe’s and Home Depot and spent over $150. The stuff we bought controlled about half of the pests but we could not find anything to kill the spiders; until we discovered Demon WP. It took three applications, but they are gone! The morning glories are looking great and I can walk our walkway with out being tied up in spider webs. This stuff really works and it only cost us about $4.00 for three applications. Our pest control charges would have been $117.

So far Demon WP lives up to its reviews. I recently bought this product and the perimeter of my home looks like a roach war zone. There is one downfall though...this product does not kill scorpions quickly because of their strong exoskeleton.

This is the best stuff around. I began seeing results within less than an hour of spraying. We found 'dead' bugs around the house for several days. A month later and I still find a few around, belly up. Since we had a roach problem I sprayed twice within a week inside and outside the perimeter of the house. In the last week I have not seen a single bug. I have used several different sprays from Home Depot and Lowes and none have been as effective as this. I would recommend it highly.
